If the main ground from the battery to the (usually) engine or a bracket attached to the engine wasn't making good contact, the electrical system could have been grounding through that one small gauge wire that melted.

Before it happens again, check the connections at the engine and battery and condition of the negative battery cable, along w/the positive cable condition and connection at the starter solenoid. If they're questionable, replace them. Be sure the grounds between the engine and firewall are there and tight.
